U1240C Series Temperature Specifications
Thermal
type Range Resolution
Accuracy ±(% of reading + as
specified below)
K
–200°C to 1372°C 0.1°C 1% + 1°C
–328°F to 2502°F 0.1°F 1% + 1.8°F
J

–210°C to 1200°C 0.1°C 1% + 1°C
–346°F to 2192°F 0.1°F 1% + 1.8°F
1. The specification above is specified after 60 minutes of warm-up time.
2. The accuracy does not include the tolerance of the thermocouple probe.
3. Do not allow the temperature sensor to contact a surface hat is energized above 30 Vrms or 60 V DC.
Such voltages pose a shock hazard.
4. The temperature calculation is specified according to the safety standards of EN/IEC-60548-1 and
NIST 175.
5. Only for U1242C.

of least significant digit)
1000 nF 0.1 nF 1.0% + 5
10 µF 0.001 µF 1.0% + 5
100 µF 0.01 µF 1.0% + 5
1000 µF 0.01 µF 1.2% + 5
10 mF 0.001 mF 1.2% + 5
1. Overload protection: 1000 Vrms for short circuits with < 0.3 A current.
2. The accuracy for all ranges is specified based on a film capacitor or better,
and after the Null function is used to subtract the test lead resistance and
thermal effect (by opening the test leads).
3. The maximum display is 12000 counts selectable

1. The frequency measurement is susceptible to error when measuring low-voltage, low-frequency
signals. Shielding inputs from external noise pickup is critical for minimizing measurement errors.
Turning on LPF (low pass filter) may help to filter out the noise and achieve a stable reading
